Description

[Detailed Description of the Invention] This invention relates to a frame member having an upper side, a side edge, a lower edge, and an opening, such as an auxiliary fitting for a sash upper frame.

Traditionally, this type of frame member was designed to save material costs.
It is formed in a shape that has the minimum necessary strength.

In other words, by opening the side of the frame, the material is saved significantly, and sometimes the upper and lower sides of the opening are connected to the frame to provide strength to the frame. ing.

However, after this type of frame member is produced in a factory, when it is loaded and transported to a warehouse or site, the opening on the side may be crushed and deformed when it is attached to the frame. An auxiliary material, such as styrofoam, was stuffed into the opening of the member.

When in use, this auxiliary material was removed and installed.

Therefore, although this type of frame member can save on material costs, it is time-consuming because care must be taken to prevent deformation during transportation and management.

This idea was made in view of the above problem, and its gist is that a locking end portion that locks on the upper and lower sides of the opening of the frame member, and a curved base that connects to these locking ends. By locking the auxiliary metal fittings, which are made of be.

Examples of this invention will be described below with reference to the drawings.

The drawing shows the case where the auxiliary metal fitting 1 of this invention is attached to the sash upper frame 2.

The sash top frame 2 has a top side 3, a side side 4, a bottom side 5, and a side side 4.
and an opening 6 provided on the opposite side, an SL-shaped locking part 7 is provided on the upper side 2, and a locking part 8 called a screw pocket is provided on the lower side 3. There is.

The auxiliary metal fittings are
a, an upper locking end portion 1a that is bent from one end of the curved base portion 1a and engages with the locking portion 7, and a curved base portion 1a.
A lower locking end 1a formed at the other end and engaging with the locking portion 8 constitutes a base, and this curved base 1
Claw portions 1d that can engage with the lower surface of the locking portion 7 are provided on both side edges of a.
, ld are bent.

9 is a wooden frame, and 10 is a picture frame.

In order to attach the auxiliary fitting 1 of this invention constructed as described above to the sash upper frame 2, first, the upper end locking end 1b is locked to the locking part 7 of the sash upper frame 2, and the curved base 1a After elastically deforming the lower end of the locking end 1c to lock the locking portion 8, the claw portion 1d is swaged in the direction of arrow A in FIG. It bites into the lower surface, and the auxiliary metal fitting 1 is locked in the opening 6 of the sash upper frame 2.

In this way, the auxiliary fittings 1 are locked at appropriate intervals in the longitudinal direction of the sash upper frame 2.

FIG. 3 shows another embodiment of this invention, in which the auxiliary metal fitting 1' used when the sash upper frame 2 is attached to the concrete frame 9' is attached. Similar to the first embodiment described above, this has a curved base 1a, locking ends 1b and 1c, and is provided with an extension 1e that stands up from the curved base 1a with respect to the surface of the curved base 1a. The extension portion 1e is welded to the reinforcement 11 so that the sash upper frame 2 can be attached to the concrete frame 9'.

12 is mortar.

As mentioned above, by using the auxiliary metal fittings of this invention, it is possible to save the material cost of the frame members and prevent deformation of the frame members during transportation and management. Since the installation work can be done without removing it, there is no need to remove the auxiliary material as in the conventional case, and in some cases, an excellent effect can be obtained in that the frame member can be installed at the same time.
